Tween 80[2]

Updated: 2026-09-12

Overview

Tween 80, also known as Polysorbate 80, is a nonionic surfactant and emulsifier widely used in pharmaceuticals, food, and cosmetics. It is derived from polyethoxylated sorbitan and oleic acid, making it highly effective in improving solubility and stability of formulations. Its versatility and safety profile have led to its inclusion in various products, from injectable medications to ice cream. The compound is approved by regulatory bodies like the FDA and EFSA for multiple applications, underscoring its reliability in industrial and consumer products.

Physical and Chemical Properties

Tween 80 is a yellow to amber viscous liquid with a mild odor. It is soluble in water, ethanol, and oils, making it a versatile ingredient in formulations requiring emulsification or solubilization. The compound has a density of approximately 1.06-1.09 g/cm³. Its nonionic nature allows it to function effectively across a wide pH range, and it is stable under normal storage conditions. However, prolonged exposure to high temperatures or strong oxidizing agents should be avoided to maintain its efficacy.

Main Applications

In pharmaceuticals, Tween 80 is used as an emulsifier in injectable formulations and oral suspensions. It enhances the solubility of poorly water-soluble drugs, improving bioavailability. In the food industry, it acts as a stabilizer in ice cream, baked goods, and beverages. The cosmetic industry utilizes Tween 80 in creams, lotions, and shampoos for its emulsifying properties. Industrial applications include its use in lubricants and textile processing. Its broad utility stems from its ability to reduce surface tension and improve mixing of immiscible liquids.

Safety and Storage

Tween 80 is generally recognized as safe (GRAS) for use in food and pharmaceuticals. However, it may cause mild skin or eye irritation upon direct contact, necessitating proper handling procedures such as wearing gloves and goggles. Storage should be in a cool, dry place away from light and moisture to maintain stability. Containers should be tightly sealed to prevent contamination or degradation. Bulk storage in stainless steel or polyethylene containers is recommended for large quantities.

B2B Procurement Guide

When procuring Tween 80, verify the purity and compliance with relevant standards such as USP, EP, or BP. Supplier certifications, including ISO and GMP, are crucial for ensuring quality. Bulk buyers should request certificates of analysis (CoA) for each batch. Price varies based on purity and quantity, with typical ranges of $5-$20/kg. Consider long-term supplier reliability and the ability to provide consistent quality. For pharmaceutical or food-grade applications, ensure the supplier meets regulatory requirements specific to your region.
